Can someone tell me what this is?

Hey guys, this is one of my Sensi Star feminized babies.

This is just 25 days from sprout under 200 real watts of cfl about 6" from the top of the plant.

Soil = Miracle grow organic (not the 3 month feedings)
Nutes = None just some epsom salt in waterings
temp = avg 77 degrees

This has been going on since the first leaves. I've never seen it before (only growing for 2 months myself) I orginally thought i burned it by misting it under the light but it's appearing on the new growth as well. Is this a calcium deficiency?

Thanks for everything guys you have been great!

might be a defficency of some sort im assuming...or it could be light burns..

i would have to say you need some nitrogen

[liquid069]

I don't know whether it's a nitrogen deficiency or pH lockout

2 dirfferent phmeters told be 6.8 to 6.0

I call lack of Nitrogen, Get some in there and Im sure it will start to come back to health.

[da_boss213]

could be nitrogen... but then i would def be expecting a lighter color of green from a nitro def... make sure ur not overwatering it and maybe switch to a some nutes like 1 once a week or so

Hey guys i added Schultz Plant food 10-15-10 at a 1/4 strength last night and now look what I got. Something is off. Should I just flush at this point? I would rather not loose the plant totally. Please help soon!

[valleyhempz]

mhmm ya try a flush could be like a salt build up or something ph could be outta wack, it didnt look like a nitrogen def too me those usually start at the top of the plant, how do you have your cfls arranged? have you tryed circling the pot with them and leaving 100watts pouring down on it with another 100 on all sides of it?

[Dopehead_680]

yo Espom salt raises the general hardness of you water, in turn raising the precipitating hydrogen ion content(pH). that means like if you didn't check the pH of your water you coulda watered them with like 7.5-8.0?theory??? not sure just kinda hypothesizing wats m.js tolerence 6.5-7 assumption? flush and stop with nutes they were unnecessary from the start IMO.

[Gr0wSm0k3S3ll]

ok now when you say 200 actuall wats you mean like the wats it says on the lightbulb or the rating..it confuses me..noob question

[liquid069]

I have 8 23watt 5500k cfl's acutally i believe i took two of them out and replaced them with 2700K's to get a broader spectrum of light. When they convert them to what they are replacing they say that 23 watt cfl is equivalent to 100watt incandescent. So if they were incandecent I would have 800watts but real cfl wattage is 184watts. So it's not the light, and the pH was perfect prior to the epsom and 10-15-10 1/4 dilution. The pH of soil was 6.8 and the runoff was 6.4. I have one other girl from seed right next to her and I just put in a clone all in the same Cab and the other one from seed looks perfect. Leaves are a little mutated but that has happened before with the Sensi Star. So i'm not sure what's going on. they have been under 24-0 for about a month now. They deffinately need transplant which I plan on doing as soon as I can correct this. I wouldn't want to put her under anymore stress. I'm going to flush in an hour with distilled water. Hopefully that will help and maybe after the weekend i'll transplant.

Let me know if there are any more thoughts and I'll post a pic of the cab with the lights in a few. Thanks guys it's much appreciated!

Yes you should flush. I think this problem is due to magnessium toxicity... you dont need to add Epsom salt every watering. A little bit of that stuff goes a long way 1 tbs per gallon of water! be careful. You probably have some lockout problems as well
and btw Miracle Gro is the worst soil for weed. I have some MG Organic at my house, its just sawdust and mulch seriously and some clear fert balls.
I use shultz potting mix, still had time release nutes but not overkill like MG

[chemicalcomfort]

what i'd would guess to have happened is that you did the epsom salt which raised the pH a bit too high and locked out some nitrogen. Then you added nutes which in turn burned it. I'd flush which some proper pH water. If after a little while it starts turning a bit yellow, add some nitrogen heavy nutes (not 10-15-10, something closer to like 20-10-10).

I'm not any kind of pro though, just my guess.

LoL, give up on that crap. Why use miracle grow ? all it does is cause fucking problems for everyone..... Go with a soil less mix that doesnt have any fucking nutrients that way you can follow the simple directions on the nutrient bottles and dont have to worry about shit like that.

Or if ur really bent on using organic shit, use the real fucking stuff..... Foxfarm ocean forest.
